Brendan Cox will encourage communities to come together in the wake of his late wife's death

The event marks the one year anniversary of Jo’s death on the streets of her constituency of Batley and Spen in Birstall, West Yorkshire.

And Mr Cox said he hoped the event will be the biggest event of its kind since the Queen’s Diamond Jubilee in 2012 with thousands of communities coming together at BBQs, picnics and bake-offs up and down the country.

Former PM David Cameron announced this afternoon he would back the initiative.
